STEM Home

Welcome

This is a tutorial on how to get the STEM source code downloaded, compiled, and running in your Eclipse Development Environment. This tutorial is mainly for committers and advanced users that want to work with the STEM source directly.

Getting Started

STEM is a Java application built on top of the Eclipse Rich Client Platform (RCP). To build and run STEM, a developer must install a supported Java Development Kit (JDK) and the Eclipse SDK. While it may be possible to compile STEM in another IDE, we strongly recommend you use the Eclipse SDK.

Prerequisites

To download and compile the STEM source, developers should first install the following components:

  1. A workstation running an Eclipse-supported operating system:
    • Windows (XP, Vista, 7)
    • Linux (GTK)
    • Mac OS X (10.5 or later)
  2. A supported Java Standard Edition (J2SE) For STEM V3.0.0M1 or above the minimum requirement is (J2SE) 8.0 JVM
    Oracle Java SE 8.0 (JRE8U65 or higher)
  3. Eclipse 4.5.4 (Mars) or above
    • Note: If you're using a 64-bit JVM, be sure to download the 64-bit version of Eclipse

Creating a STEM Development Environment

The process for building STEM consists of several steps. The steps should be followed in this order:

Set up your Eclipse SDK

Before you attempt to checkout and compile the STEM source code, some additional features must be installed into your Eclipse SDK.

Install Required Eclipse Features

This installation guide requires that Eclipse EGit be installed. In addition to EGit, much of STEM is built using modeled code generated by the Eclipse Modeling Framework (EMF). To extend these models, or edit existing models, EMF must be installed into your environment.

  1. Launch your Eclipse SDK
  2. Open the Eclipse Software Installer by opening the Help menu and choosing Install New Software
  3. When the Install dialog opens, select the Juno repository from the drop-down menu. Wait while the list of additional features loads.
    • Install EGit
      1. Expand the Collaboration category by clicking the arrow next to it
      2. Select Eclipse EGit
    • Install the Eclipse Modeling Framework (EMF)
      1. Expand the Modeling category by clicking the arrow next to it
      2. Select EMF - Eclipse Modeling Framework SDK
  4. Click Next
  5. Verify that EGit and EMF are in the list of features to install. Click Next
  6. Read the license agreement and, if you accept, choose I accept the terms of the license agreement . Click Finish
  7. Wait while the features install into your Eclipse SDK
    This step may take up to 10 minutes to complete
  8. When the installer finishes, it'll prompt you to restart. Click Restart Now

Checkout and Build the STEM Source Code

Once your Eclipse environment is set up, you're ready to checkout the STEM source code. The STEM Project provides an Eclipse Team Project Set (PSF) that'll help you quickly get the STEM Source code checked out.

Checkout the STEM Source Code from a Project Set File

Important Note: Before beginning these steps, committers should read these important details about checking out from Git.

  1. Launch your Eclipse SDK
  2. When prompted to Select a workspace, choose a new path that does not contain an existing workspace. This creates a new workspace.
    Important Note: Eclipse and STEM work best when the workspace path contains no whitespace characters (spaces, tabs, etc). Example: C:\workspace\
    Switch to the GIT Repository Exploring perspective (this seems to be necessary to workaround EGit bugs)
  3. Open the File menu and choose Import
  4. When the Import dialog opens, expand the Team category by clicking the arrow next to it
  5. Choose Team Project Set and click Next
  6. On the Import a Team Project Set page, choose URL and enter the URL for the correct Project Set file
    • For new users (non-committers):
      http://www.eclipse.org/stem/psf.php
    • For Eclipse committers (SSH):
      http://www.eclipse.org/stem/psf.php?r=ssh&u=YOUR_COMMITTER_USERNAME
      Note: Replace YOUR_COMMITTER_USERNAME with your committer username, not e-mail address, in the above link
    • For Eclipse committers (HTTPS):
      http://www.eclipse.org/stem/psf.php?r=https
      NOTE: for HTTPS the password is different than for the rest of eclipse. You can generate a password here: https://git.eclipse.org/r/#/settings/http-password
  7. Click Finish

  8. Wait while Eclipse checks out and imports the STEM source code into your environment
    Depending on your connection speed, this step may take over an hour to complete. Have some coffee and come back.
  9. Trouble shooting for SSH. If you're getting authentication exceptions checking out the STEM source code, make sure you've configured SSH in the Eclipse preference settings correctly. Instructions for doing this can be found here [SSH Configuration]. Do not upload your public key to GitHub, instead you need to upload it to Gerrit here: [Gerrit SSH Upload].

Apply the Target Platform

Once the checkout completes, there will likely be hundreds (or thousands) of build errors. STEM uses what's called an Eclipse Target Platform to manage the rest of the dependencies that must be installed to completely build and run STEM. The following steps will help you in applying the target platform.

Important Note About Target Platforms: The target platform represents which version of the Eclipse Platform to compile and run STEM in.
  1. In the Eclipse SDK, open the Preferences dialog. Select the Window menu and choose Preferences
    On Mac OS X, it's under the Eclipse menu
  2. In the Preferences dialog, expand the Plug-in Development category
  3. Select the Target Platform option under Plug-in Development category
  4. Select the STEM3 Target Platform by clicking checkbox
    STEMtarget3.png
  5. Wait while Eclipse loads the Target Platform.
    Depending on your connection speed, this step may take up to 30 minutes to complete.
  6. Make sure STEM is built completely. Under the Problems tab, there should be no Errors (Warnings are OK)

  7. If you are still seeing errors, try cleaning the workspace
    1. Select the Project menu and choose Clean...
    2. In the Clean dialog, choose Clean All Projects
    3. Click OK
    4. Wait for Eclipse to clean and re-build STEM

Migrating your environment to STEM V3.0.0M1 (For STEM developers beginning October 21, 2015)

If you already have a development environment (Eclipse 3.x workspace) set up and want 
a fast path to migrate to Eclipse 4.x (STEM 3.0.0M1 and above) 
the following is a fast path to update your workspace. 
First be sure to Install Java 8 on your Machine (both JDK and JRE). 
Open a terminal window and type java -version to make sure it's installed.
  1. Do a git PULL to update your current workspace with the latest and merged changes. Your build will break but don't worry about that.
  2. Download and install the current version of Eclipse 4.x
  3. Point your new Eclipse at your workspace. It will ask if you want to migrate. Say yes.
  4. Your build will still be broken. Go to org.eclipse.stem.releng.targetplatforms and check that you see STEM3.target If you see it then you correctly updated GIT in step (1). If you don't see it, then update (pull) the latest.
  5. Got to>Eclipse>Preferences>plugindevelopment>targetplatorm (or >Windows>Preferences>plugindevelopment>targetplatorm) and apply the STEM3.target
  6. You may have to apply the target twice as it is reported to fail the first time.
  7. Got to>Eclipse>Preferences>Java or >Windows>Preferences>Java and make sure you point BOTH the Compiler and the Installed JREs to Java 8.
  8. Run a Clean>Clean All

Build the STEM Denominator Data

Once STEM is built, it's time to build the STEM data sets. This process transforms the data from a raw, human-readable format to STEM modeled data files that are readable by scenarios, models, decorators, etc.

  1. In the Eclipse SDK, in the Package Explorer , scrolls down to the org.eclipse.stem.internal.data project
  2. Expand the org.eclipse.stem.internal.data project by clicking the arrow next to it
  3. RIGHT click on the update.xml file
  4. In the context menu, highlight Run As and click on Ant Build
  5. Wait while the data builder runs.
    This will take up to 10 minutes
Please Observe: There is an issue with the latest version of Eclipse Oxygen on some platforms that causes the Ant build to fail. 
The default path for eclipse.pdebuild.home in Ant properties has a final dot (.) at the end of the path value. 
For example, you may see the value C:\Users\account_name\Desktop\Stem\eclipse-rcp-oxygen-1a-win32-x86_64\eclipse\plugins\org.eclipse.pde.build_3.9.300.v20170515-0912\. This issue has been reported particularly on mac. Removing this final dot(.), or adding (/) after resolves the issue. The bug has been reported to Eclipse.

Advanced Topics

The following are advanced topics that existing developers may be interested in. If you're new to STEM development, you can skip this section.

Getting the Earth Science Data

The STEM project contains several gigabytes of "earth science" data derived from NASA and NOAA satellite imagery. These data include global elevations, air temperatures, rainfall, vegetation coverage, etc. By default, this data is not included when you checkout STEM. These steps will help you checkout and build the earth science data for use in your STEM development environment.

WARNING The STEM Earth Science Data is several gigabytes in size. The checkout may take several hours to finish and will use a lot of disk space

  1. Complete all the steps above and make sure STEM is built in your Eclipse SDK and can be launched
  2. In your Eclipse SDK, go to the File menu and select Import
  3. In the Import wizard, expand Team , select Team Project Set , and click Next
  4. On the Import a Team Project Set page, choose URL and enter the URL for the correct Project Set
